2020-03-28 03:55:21 | BioPortfolio


In an 8-week randomized double-blind placebo-controlled outpatient pilot trial the efficacy of pregabalin in the treatment of alcohol dependence will be studied in 50 treatment-seeking outpatients. Participants will report drinking a minimum of 5 standard drinks for men or 4 standard drinks for women at least 4 days per week over the past 28 days.


In an 8-week double-blind placebo controlled outpatient clinical trial, the safety and efficacy ofpregabalin will be tested in 50 outpatients with Alcohol Use Disorder.Participants will be randomly allocated (1:1) to receive pregabalin or an identical-appearing, inert placebo. All study medication (placebo and pregabalin) will be over-capsulated with riboflavin to assess compliance. Pregabalin will be administered in 75 mg and 100 capsules; placebo capsules will appear identical to the pregabalin capsules. Participants in both study arms will receive the same number of capsules. Pregabalin will be titrated over a 3-week period to the FDA maximum (600 mg per day) or the maximum tolerated dose.

Study visits will occur daily for the first 4 days of the study period, then approximately every other day for the remainder of week 1, for a total of 5 study visits (study days 1,2,3,4, and 5 or 7). During the second week, study visits will continue every other day for a total of 3 study visits (study days 8,10, and 12). During the remainder of the 8-week study period, study visits will occur twice weekly. There will be two visits during a post-study taper week. One visit per week will be with the research psychiatrist. All participants will have a weekly supportive behavioral treatment session with the research psychiatrist using a manual designed for pharmacotherapy trials in subjects with alcohol use disorders
